DISCHARGED BATTERY Using booster cables (jump leads) from a donor battery, or a battery fitted to a donor vehicle, is the only approved method of starting a Discovery with a discharged battery.
Vehicles with automatic transmission cannot be restarted by push or towing.
USING BOOSTER CABLES If a donor vehicle is to be used, both vehicles should be parked with their battery locations adjacent to each other. Ensure that the two vehicles do not touch.
Apply the handbrakes and ensure that the transmission of both vehicles is set in neutral (‘P’ or Park for vehicles with automatic transmission).
Always wear appropriate eye protection when working with batteries.
Turn off the starter switch and ALL electrical equipment of BOTH vehicles, then follow the connection instructions on the following page.
During normal use, batteries emit explosive hydrogen gas sufficient to cause severe explosions capable of causing serious injury - keep sparks and naked lights away from the engine compartment.
DO NOT attempt to start the vehicle if the electrolyte in the battery is suspected of being frozen.
Make sure BOTH batteries are of the same voltage (12 volts), and that the booster cables have insulated clamps and are approved for use with 12 volt batteries.
DO NOT disconnect the discharged battery.
DO NOT connect positive (+) terminals to negative (-) terminals, and ensure booster cables are kept away from any moving parts in the engine compartment.
Take care when working near rotating parts of the engine.
